Model 1: no covariates were adjusted. Model 2: age, gender and race were adjusted. Model 3: age, gender, race, education level, BMI group, smoking status, physical activity, alcohol, hypertension, PIR, cotinine and diabetes were adjusted. NHHR: Non-High-Density Lipoprotein Cholesterol to High-Density Lipoprotein Cholesterol Ratio, CI: Confidence Interval, FEV1: Forced Expiratory Volume in 1 s, FVC: Forced Vital Capacity, FEV1/FVC: Ratio of Forced Expiratory Volume in 1 s to Forced Vital Capacity. Bold values in the table indicate statistical significance (p < 0.05).
